Gathering is a classic decorative technique. It's easy with this, special foot, which is especially useful for sewing flounces on cushions and curtains or for attaching gathered seams on children's clothing. You can simultaniously stich a nd gather two layers of fabric quickly and easily. This foot fits most models of Pfaff sewing machines, except the older 300 and 900 series, and the 6085/86/87 models.
